/* dot language does not specify max. point size for font.
 * gml4gtk does limit it to 255 to avoid crashes.
 * dot allows fp humber as 10.0 when int is expected.
 * at test it appears dot point-size has a undocumented max. of 255
 * dot message is:
 * Warning: POINT-SIZE value 256 > 255 - too large - ignoredin label of node h3
 * Warning: POINT-SIZE value 2147483648 > 255 - too large - ignoredin label of node h4
 * Warning: POINT-SIZE value 4294967296 > 255 - too large - ignoredin label of node h5
 * gml4gtk warns but limits the value to 255 and does not ignore the labels.
 * dphl_chk_pointsize(): limiting point-size 256 to 255 max.
